I make of that that Autodesk wants to sell their software. Note Windows 8.1 system requirements •Processor: 1 gigahertz (GHz) •RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit) •Hard disk space: 16 GB (32-bit) or 20 GB (64-bit) •Graphics card: Microsoft DirectX 9 graphics device with WDDM driverBut would YOU recommend those measly specs to someone coming to you for buying advice? Would those measly specs provide YOU "satisfactory" performance? Yeah, Windows will "run" with that hardware just like 3ds will "run" with the 4600. But that, IN NO WAY, implies performance will be satisfactory and not bottlenecked. That said, the 4600 is not a chump for an integrated GPU, but still cannot keep up with most dedicated cards. If the goal here is to buy on the tightest budget, then fine, go with an integrated solution. But if you want the best performance your budget will allow, gobs of RAM and the best graphics card you can afford is the way to go, then the best CPU. But don't forget the last, but perhaps the most critical purchasing decision, the PSU. I recommend at least 80-Plus Bronze, preferably Gold and of course with ample power.
